Sports

Soccer, commonly known as football or soccer, is a team sport played between two teams of 11 players each. It is played on a rectangular grass field, or occasionally on artificial turf, with a goal at each end of the field. The object of the game is to score by maneuvring the ball into the opposing goal; only the goalkeepers may use their hands or arms to propel the ball in general play; the rest of the team generally uses their feet to kick the ball into position, though occasionally they may use their torso or head to intercept a ball in mid air.

Soccer is played in accordance with a set of rules, known as the Laws of the Game. The game is played using a single round ball (the football) and two teams of eleven players each compete to get the ball into the other team’s goal, thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals, then the game is a draw. The primary rule is that the players (other than the goalkeepers) may not intentionally touch the ball with their hands or arms during play (though they do use their hands during a throw-in restart). Although players usually use their feet to move the ball around, they may use any part of their bodies other than their hands or arms.

In typical game play, players attempt to propel the ball toward their opponents’ goal through individual control of the ball, such as by dribbling, passing the ball to a team-mate, and by taking shots at the goal, which is guarded by the opposing goalkeeper. Opposing players may try to regain control of the ball by intercepting a pass or through tackling the opponent who controls the ball; however, physical contact between opponents is limited. Soccer is generally a free-flowing game, with play stopping only when the ball has left the field of play, or when play is stopped by the referee. After a stoppage, play recommences with a specified restart.

The Laws of the Game do not specify any player positions other than goalkeeper, but a number of player specialisations have evolved. Broadly, these include three main categories: strikers, or forwards, whose main task is to score goals; defenders, who specialise in preventing their opponents from scoring; and midfielders, who dispossess the opposition and keep possession of the ball in order to pass it to the forwards; players in these positions are referred to as outfield players, in order to discern them from the single goalkeeper. These positions are further differentiated by which side of the field the player spends most time in. For example, there are central defenders, and left and right midfielders.

The ten outfield players may be arranged in these positions in any combination (for example, there may be four defenders, four midfielders, and two forwards, or three defenders, three midfielders, and four forwards), and the number of players in each position determines the style of the team’s play; more forwards and fewer defenders would create a more aggressive and offensive-minded game, while the reverse would create a slower, more defensive style of play.

While players may spend most of the game in a specific position, there are few restrictions on player movement, and players can switch positions at any time. The layout of the players on the pitch is called the team’s formation, and defining the team’s formation and tactics is usually the prerogative of the team’s manager.

The basic equipment (kit) players are required to wear includes a shirt, shorts, socks, footwear and adequate shin guards. Players are forbidden to wear or use anything that is dangerous to themselves or another player (including jewellery or watches). The goalkeeper must wear clothing that is easily distinguishable from that worn by the other players and the match officials.

A number of players may be replaced by substitutes during the course of the game. The maximum number of substitutions permitted in most competitive international and domestic league games is three, though the number permitted may be varied in other leagues or in friendly matches. Common reasons for a substitution include injury, tiredness, ineffectiveness, a tactical switch, or as a defensive ploy to use up a little time at the end of a finely poised game. In standard adult matches, a player who has been substituted may not take further part in the match.

A game is officiated by a referee, who has “full authority to enforce the Laws of the Game in connection with the match to which he has been appointed” (Law 5), and whose decisions are final. The referee is assisted by two assistant referees. In many high-level games there is also a fourth official (and in the world cup a fifth official), who assist(s) the referee and may replace another official should the need arise.

Under the Laws, the two basic states of play during a game are ball in play and ball out of play. From the beginning of each playing period with a kick-off (a set kick from the centre-spot by one team) until the end of the playing period, the ball is in play at all times, except when either the ball leaves the field of play, or play is stopped by the referee. When the ball becomes out of play, play is restarted depending on how it went out of play.
